All changes should be made via pull requests on GitHub.

When issuing a pull request, please add a summary of your changes to the CHANGELOG.md file.

We follow the same syntax as CocoaPods' CHANGELOG.md:

1. One Markdown unnumbered list item describing the change.
2. 2 trailing spaces on the last line describing the change.
3. A list of Markdown hyperlinks to the change's contributors. One entry per line. Usually just one.
4. A list of Markdown hyperlinks to the issues the change addresses. One entry per line. Usually just one.
5. All CHANGELOG.md content is hard-wrapped at 80 characters.

CI jobs for the latest official Swift and Xcode releases should be kept up to date based on the available Xcode versions that can be found in the actions/virtual-environments repo.
